TILE-GLAZING MACHINE.

Specification of Letters Patent.

Patented Dec. 7, 1915.

Application filed September 11, 1913. Serial No. 789,229.

To all whom it may concern: I

Be it known that I, HUGO S'roMMnL, a citizen of the United States, residing in Elberon, county of Monmouth, and State of New Jersey, have invented a certain new and useful Tile-Glazing Machine, of which the following is a specification. This invention is a machine for coating or glazing tiles, and the objects of the invention are: to simplify the construction, cheapen the cost of production, and secure increased efliciency both in the quality and quantity of the coated tiles, over that of the machines heretofore used.

One of the salient features of the invention consists in the employment of a laminated liquid conveyer, the base of which consists preferably of rubber, said conveyer being provided with a continuous longitudinal channel intermediate its edges. In this channel is positioned a suitable porous or absorbing medium, 6. 9., cheese cloth for the coating solution. Exteriorly of the absorbing medium is a perforated member of suitable material, c. a celluloid band whereby a smooth uniform contact between the tiles and the conveyer is assured, said celluloid serving as a base or support for the external 'conveyer.

A further feature of the invention consists of an extension or well in communication with the tank containing the coating solution. The greater portion of the conveyer is immersed in the solution contained in said well whereby it is charged with the solution and remains thus charged until brought into engagement with the tile to be coated, whereupon a pressure roll engaging the back of the tile forces the same against the conveyer, thus causing the coating solution to be squeezed out of the conveyer ed upon the face of the tile.

Another feature of the invention, and one of pronounced practical importance, consists in the accessibility of the working parts of the structure, the construction being such that the conveyer and its cooperating parts may be readily removed from the well for the purposeof cleaning or repairing the parts and without interfering with the tank 4 the driving mechanism of the conveyor.

Features of the invention other than those eferred to, will be clear from the hereinj fter detailed description.

In the accompanying drawings I have or top covering, preferably wire mesh of the and depositillustrated one practical embodiment I of my invention. This embodlment is,

however, to

be understood as illustrative only, and not ing means for regulating the amountof coating solution carried by the conveyer.

In said drawings, A designates a flexible liquidconveyer, stretched about a pair of rollers B and ,B, which rollers are revolu bly mounted one above the other, in a frame work 0. The frame work C is suspended for its greater portion in a narrow exten sion D, of a tank or container D which tank and extension are'mounted in any suitable form of standards, not shown. The frame'suspension is effected'by means of projecting arms c, integral with the frame, and adapted to be bolted, or otherwise secured,'to the brackets (Z, mounted on the tank extension D. Theroller B is mounted on the shaft E in fixed journals 6, and the roller B is mounted on the shaft E, carried by slidable journals 6. The tension on the conveyor A may be regulated by any means such as set screws 7, whichare thread ed through the frame C and engagedwith the upper faces ofthe slidable bearings e. The shaft E means of lubricant supply pipes F.

At both ends of each of the rollers B and B and fixedly mounted'on the shafts E and E are sprocket wheels G and G, respectively. Around each pair of sprockets, on the respective sides of the roller, pass sprocket chains H, for the purpose of revolving the said rollers in timed relation, which rollers are operated by means of a belt, not shown, cooperating with the fixed and loose rollers I andlfmounted on short shaft E which is properly positioned in a bearing 00, supported by the tank D, in

alinement, and in end-abutting relation to" Fig. 5 is a perspective view of a portion of the solution containing illustratis kept properly lubricated by the endless extent of the conveyer.

. in, journals the shaft E. The short shaft E operates the shaft E through clutch members U and V.

The conveyer A, for the properoperation of the machine should pass from 'one roller to the other, at substantially constant speed, and this isbrought about by securing said belt along its edges to the sprocket chains- H, said securing means being shown more particularly in Figs. 3 and 4:. Thisrsecuring of the edges of the belt to the sprocket chains occurs at fixed distances throughout Each of the means for fastening the conveyer to the chains consists in a screw J which passes through a washer y, through the conveyer A, through a spacing member 7" and then threads into a top in the solid blocks h of each of the chains H. Manifestly, the turning of the fixed pulley I, on the shaft E willrotate the sprockets G, with the result that the conveyer A is positively driven.

The tank D is adapted to contain considerable depth of thetile coating or glazing fluid, and a corresponding depth is consequently tension D thereof. It will thus be apparent that the frame G is suspended in the. soluion, so that the conveyer A,.in its travel about the supporting rollers 13 and B, will pass through he. glazing fluid and will, when the. machine is in operation carry a portion of said fluid up and over the roller 13.. I

The tiles K to be glazed are fed to the liquid conveyer A on an endless apron L, which passes over a roller Z, and are received and carried away after being. coated by means of an apronvL, passing about the roller Z. q

A pressure roll N is preferably made of leather, rubber, or some other slightly cushioning material is provided, and'is. mounted M. for vertical -.adj3ustment in slideways m in thezframe C. This ismade by means of set screws, n threaded through theupperportion of the frame, and co'riperating with springs O, in engagement with the underside of the journals. The rollers N andrB. are driven at substantially the same speed, by means ofgearsX and X;

The gear X is carried by short. shaft a in I alinement, and.in--end-abutting relation to the shaft n,-said shaftbeing mounted in a bearing or, preferably cast integral with the bearing'w. which. supports the shaft. The-inner .endof the shaft n hasfixed thereto a clutch member V whichcooperates with the, clutch member U on the adjacent end: of vthe shaft 72,.

I do not. wish to restrict myself to the PQCifi form of liquid a onveyer herein h wn; y t I- ha e. found a QQIWQY pt th structureiherein illustrated particularly well dapt d to. carryout thefun t enswhich it maintained at all times in the ex-- i called upon to perform. This specific form is'shown, more particularly, in Figs. 3 and l. It embodies. a base P of rubber or other slightly flexible material, and is provided-within its edges with a channel p, extending uninterruptedly around the conveyer. This channel 29 is for the reception of a plurality of layers of flexible porous or absorbent material, 6. 9., cheese cloth, which fills up the channel so that the top layer of cloth is substantially flushwith the thickest portion of the body P. Exterior of the body P, and over the porous material is a perforated sheet R of some fairly rigid material, e. 9., celluloid, which perforated sheet serves as a semi-rigid backing for the top covering of the conveyer. The conveyer has a top covering of gauze'or fine mesh wire S. It will thus be manifest that, in passing through the solution the porous or absorbent portion Q of the conveyer will take up a portion of said solution, and the same will be carried upon the rotation of the conveyer to the supporting roller B, and over said roller, to be applied to the under side of the tile as it passes between said conveyer and the pressure rollM. Vhile, however, the tile is in this position between theconveyer and the pressure roller, the pressure of said roller causes the tile to be pressed slightly down upon the liquid conveyer with the result that the coating solution resident in the porous portion Q; there of, is squeezed out through the perforated sheet R and through the wire S into inth inate contact with the under face of the tile for. the purpose of applying the coating thereto.

Another feature of the invention is the embodiment of a wiper which is employed, more particularly, for the purpose of uniformly distributing the solution carried by the conveyer throughout the extent thereof. This wiper T is formed preferably of fiber or some other material which will not tend to scratch or destroy the conveyer, and is, in length, equal to the width-of said conveyer. It is attached to an innerface ofthe extension D of the tank near the top edge thereof by means of bolts 25. Wiper T is thus positioned at right angles tothe direction of travel of the .conveyer and is provided with an inwardly extending flange t which is adapted to engage with the exterior face ofsaidconveyer. T The free edge of the wiper may be brought into desired contact withthe conveyer. by means of adjustable A salient feature of this invention resides in the simplicity and accessibility of the parts thereof. For many reasons, it is de sir-able that the frame 0, and the parts cooperating therewith be so mounted on the tank extension D that said frame and component parts may be lifted out en masse for the purpose of cleaning, etc. For this reason, the shaft 72, which carries the pressure roll and the shaft E, on which the roller B is fixed, terminate on the outside of the frame and on the driving side thereof, in the clutch members U and U respectively. The ends of the shafts n and E which abut the adjacent ends of the shafts n and E, are provided with clutch members V and V, complementary to clutch members U and U respectively. It will thus be seen that, when it is desired to detach the frame C and the tank extension D, it is only necessary to remove the bolts and turn the shafts n and E into such position that the male clutch members of the clutches U, U and V, V are vertically disposed Whereupon the entire frame may be lifted bodily out of the solution.

It will be manifest from the foregoing description that my invention is of an ex tremely simple and novel character, none of the mechanism of which is apt to get out of order, or need careful attention, the device being highly efficient in tion and producing much superior results to the machines now in use.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is 1. Ina tile coating machine, an endless liquid conveyer belt embodying a base mem her, a plurality of plies of absorbent material and a non-absorbent facing superimposed upon said base member, and secured igainst shifting relatively thereto, and means for charging said conveyer belt with i tile glazing solution.
